The specific enthalpy of vaporization (usually represented by the letter H with a carat above it) is generally given as units of energy per unit mass or per mole. If given in terms of per unit mass, the mass boiled can be calculated by dividing the energy input by the specific enthalpy. If given in terms of per mole, first divide the energy by the specific enthalpy then multiply the result by the mass per mole.
The enthalpy of vaporization (H_vap) is the amount of energy required to convert a unit mass of a liquid into vapor without a change in temperature. To calculate the mass of liquid boiled by 1 kJ of energy, you can use the formula: mass = energy / H_vap. By dividing the 1 kJ (or 1000 J) of energy by the H_vap value (in J/kg), you can determine the mass of the liquid that can be vaporized. This calculation is crucial in thermodynamics and engineering applications involving phase changes.
Enthalpy is used to calculate the energy required to vaporize a volume of liquid by applying the concept of latent heat of vaporization, which is the amount of energy needed to convert a unit mass of liquid into vapor without changing its temperature. The total energy required for vaporization can be calculated by multiplying the mass of the liquid by the specific enthalpy of vaporization (ΔH_vap) at the given temperature. This relationship allows us to determine the total energy input necessary to achieve complete vaporization of the liquid.
Fusion, typically referring to nuclear fusion, is not directly used to calculate the energy required to vaporize a volume of liquid. Instead, the energy required for vaporization is calculated using the latent heat of vaporization, which is the amount of energy needed to convert a unit mass of a liquid into vapor without changing its temperature. This is determined by multiplying the mass of the liquid by its specific latent heat of vaporization. Fusion processes might contribute to broader energy concepts but are not relevant for this specific calculation.
The energy needed to change a substance from a liquid to a gas is called the enthalpy (or heat) of vaporization.
1kJ x 1/Hvap x g/mol liquid
1kJ x 1/deltaHvap x g/mol liquid.
The latent heat of vaporization (Hvap) is used to calculate the mass of liquid boiled by 1 kJ of energy using the formula: mass = energy / Hvap. This formula helps determine the amount of liquid that can be converted to vapor with a given amount of energy input.
The formula to calculate the mass of liquid boiled by 1 kJ of energy is: mass = 1 kJ / delta Hvap. ΔHvap is the molar enthalpy of vaporization, which is the amount of energy required to vaporize one mole of a substance. By dividing the energy input (1 kJ) by the enthalpy of vaporization, you can determine the mass of liquid that will be vaporized.

The energy needed to go from a liquid to a gas is referred to as heat of vaporization.
AnswerHeat of vaporization.
The heat of fusion is used to first convert the volume of liquid to its solid form, then the heat of vaporization is used to convert the solid to vapor. By summing the two energy values, you can calculate the total energy required to vaporize the liquid volume.
